Benefit
When attacking with a melee weapon that you have both weapon focus and weapon specialization in, you add 1.5 times your strength modifiers to damage rolls while wielding a weapon one handed. If wielding a weapon two handed, you add 2 times your strength modifier to damage rolls. However, striking blows in such a way is highly risky, and while using this feat you take a -2 penalty to AC. You may not use this feat while using the weapon finesse feat. You cannot combine this with other attacks that raise your strength damage to hits such as Overhand Chop (Fighter Two Handed Fighter).

Normal
When wielding a weapon one handed, you add only 1 times your strength modifier to damage, or 1.5 times your strength modifier with two handed weapons. In addition, while attacking, you don not take a -2 penalty to AC.
